Electron transport chain

Electron carriers take high energy electrons (picked up from glycolysis, link and krebs) to a group of enzymes in the folds of the mito

These enzymes takes high energy electrons and pass them down the line. As the electron is passed, H+ ions are pumped to the outer compart of the mito

This ion gradient is used to run the ATP production by electron transport chain (chemiosmosis) aprox 32 ATP

By the end the electron is back to its ground state energy and has to be picked up and carried away so that the process can continue. Oxygen is the final electron acceptor and water is the last product made as o2 picks up the electron and then combines with a H+ ions
